Participants

Reaction Steps

10 g of dimethylaspartic acid was placed in a 250 ml round-bottom flask, and 40 ml of water was added and stirred for 30 minutes. Then, 7.36 g of concentrated sulfuric acid (concentration: 98%) was slowly added to the flask. After the addition, a reaction was conducted for 2 hours. The reaction solution was concentrated, and azeotroped with 100 ml of toluene to further remove the water. Afterwards, the product was dried under high vacuum, and ground by using a spatula to obtain 15.34 g of N,N-dimethylaspartic acid sulfate as tawny oil (Yield: 95.33%).
